PICTON, who had been watching with intense anxiety the contest maintained by the 42nd and 44th British Regiments in their exposed situation, and who had become convinced of the utter hopelessness of obtaining any efficient support from the Allied Cavalry then in the field, could no longer restrain his impatience to fly to the rescue of the devoted Squares; and, as a substitute for Cavalry, he decided upon immediately assailing that of the Enemy with his own oft tried Infantry. With this view, he united the Royals (under Lieutenant Colonel COLIN CAMPBELL) and the 28th Regiment, both of which Corps were at that moment standing in Column at quarter distance. Led on by both PICTON and KEMPT, the united Column, with loud shouts, boldly advanced into the midst of the Enemy's Cavalry; the whole extent of ground along its front appeared to swarm with Lancers, _Chasseurs à Cheval_, and _Cuirassiers_, a considerable portion of whom were now seen rapidly forming for an attack upon the Column; but PICTON constantly on the alert, and at the same time desirous of arriving at such a distance as would enable him to present an efficient flank fire in support of the 44th Regiment, continued advancing until the last moment, when he suddenly formed it into Square. The repeated and furious charges which ensued, were invariably repulsed by the Royals and the 28th, with the utmost steadiness and consummate bravery; and although the Lancers individually dashed forward and frequently wounded the men in the ranks, yet all endeavours to effect an opening, of which the succeeding Squadron of Attack might take advantage, completely failed. The ground on which the Square stood was such that the surrounding remarkably tall rye concealed it in a great measure, in the first attacks, from the view of the French Cavalry until the latter came quite close upon it; but to remedy this inconvenience, and to preserve the impetus of their charge, the Lancers had frequently recourse to sending forward a daring individual to plant a lance in the earth at a very short distance from the bayonets, and they then charged upon the lance flag as a mark of direction. The advance of the Royals and the 28th had been almost immediately followed, under the same form, by that of the 32nd Regiment, which, having reached a convenient distance, halted, and formed Square so as to support, at the same time, by a flank fire, the Royals and 28th, and the Square of the 79th Highlanders, which latter Regiment constituted a connecting link with the 95th British Regiment upon the extreme Left. Upon the advance of the Regiments belonging to KEMPT's and PACK's British Brigades, BEST's Hanoverian Brigade occupied the Namur road in their rear, along which the Landwehr Battalions Lüneburg, Osterode, and Münden (respectively commanded by Lieutenant Colonel RAMDOHR, Major REDEN, and Major SCHMID) were deployed, while the Landwehr Battalion Verden (under Major DECKEN), also in line, was posted somewhat in advance.
